Types of Prescription Lenses and Their Features

When it comes to prescription eyeglasses, there are various types of prescription lenses available nowadays, catering to the individual needs of every patient. Let’s take a look at each one of these lenses.

Single Vision Lenses

Single vision lenses are recommended if the patient needs correction for a single field of vision i.e. either for distant objects or close-by items. Single vision lenses contain the same power over the complete lens. These lenses can rectify farsightedness, nearsightedness, and astigmatism.

Bifocal Lenses

Bifocal lenses have two different prescriptions in a single lens. The basic purpose of these lenses is to provide the maximum balance between near vision and distant vision focus. Generally, the lens’ upper part is used for distant vision and the lower part is for viewing the nearby objects such as reading. The two powers are divided with an obvious line in the center or lower part of the lens.

Progressive Lenses

These lenses are called ‘no-line bifocals’ because they contain multiple vision levels within a single lens. Their major benefit is that unlike the bifocal or trifocal lenses, these lenses support multiple vision levels, with their focus range precisely shifting in a gradient-like manner with distant vision on the top area progressing downward to intermediate and near-sight vision adjustment at the bottom.

These lenses contain a wide range of vision fields which results in vision correction which is closest to the natural vision.

Premium Progressive Lenses

The premium progressive lenses, also known as the Varilux Series, are the most advanced and latest progressive lenses. These lenses have all the advantages of the typical progressive lenses, while rectifying the ‘off-balance’ feeling which is sometimes experienced with the progressive lenses. These lenses use the most advanced Nanoptix technology, in order to eliminate the off-balance feeling and give you clearer vision from top to bottom and right to left.
